I've always gotten the impression that TDD is one of those things that many people think they should do, but have a hard time making a habit (so it's not surprising it gets more talk than action). Speaking of books, Real World Haskell covers testing pretty early on; granted, being Haskell, whether or not it qualifies as "Real World" is still a little subjective at this point.
